My hon. Friend has put his finger on it. It is important to give every encouragement to Vietnam to make progress. I agree with my hon. Friend that it is extremely important that the United States should do what it can to remove trade restrictions and to help with economic development in Vietnam.

The United States has imposed involuntary returns. Of course, it is right to have a hang-up, to put it bluntly, about its experiences in Vietnam in the 1960s, but times have changed and conditions and circumstances are quite different. The United States has an obligation to assist the British Government and the people of Hong Kong to find a solution to the problem. Our Government's first duty is to Hong Kong and its people, and we look to them to take a positive lead, but with the help of the United States. That is the least that we can do for the people of Hong Kong.
